按照你说的方法Where后面老是有一对括号

@Select("sele * from user ${ew.customSqlSegment}")
List<User> selectAll(@Param(Constants.WRAPPER) Wrapper<User> queryWrapper);

LambdaQueryWrapper<User> lambdaQueryWrapper = Wrappers.<User>lambdaQuery();
lambdaQueryWrapper.like(User::getName,"雨");
 List<User> users = userMapper.selectAll(lambdaQueryWrapper);

实际的请求SQL：sele * from user WHERE (name LIKE ?)
